This set of two high-definition documentaries takes viewers to places of remarkable scenery and rich cultural history. The first program visits the Peruvian forests, mountain passes, and stunning vistas of Machu Picchu; the medieval cities and lush vineyards and olive groves of Umbria in the heart of Italy; and the Languedoc region of southwestern France, where the ruined castles of the persecuted Cathar sect are found. The second program takes viewers along the 4,000 miles of the Great Wall of China and the ancient trade route of the Silk Road. The programs are presented in both Blu-ray and standard DVD formats on this two-disc set, which also includes digital copies.
